Improvement in lamps



UNITED STATES PATENT OFFICE.

LEWIS J. ATWOOD, OF WATERBURY, CONNECTICUT.

IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 4] .751, dated March 1, 1864.

.To all whom it may concern.-

Be it known that I, LEWIs J. Arwoon, of Waterbury, in the county of New Haven and State of Connecticut, have invented, made, and applied to use a certain new and useful Improvement in. Lamps; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexeddrawings, making part of this specification, wherein- Figure 1 is a vertical section of my improvement, and Fig. 2 is a plan of the same.

Similar marks of reference denote the same parts.

Lamp-burners have heretofore been made with a hinge connecting the chimney-holder to the shell of the burner, and various devices, such as stop hinges and projections, have been employed to prevent the chimney from swinging too far back, so as to risk breaking the same by the end striking the table.

The nature of my said invention consists in a hinged brace-rod, connected in a peculiar manner at one end to the ring for the chimney, and at the other end sliding through a hole in the ratchet-cap or burner-shell, whereby the device is contained entirely within the burner, and is much stronger and less liable to be bent or broken than any of the devices heretofore resorted to. In the drawings, a is the screw-rin g for the top of the reservoir. 1) is the shell of the burner. c is the ratchet-cap; r], the Wick tube; 6, the wick-raiser f, the deflector, and g the chimney-holder, all of any usual or desired construction. h is the spring-catch taking a notch in the ratchet-cap c at i.

k is the hinge, one leaf of which is attached to the shell b, and the other end to the chim- 'ney-holder g by rivets.

Through the hinge k, (in the leaf that is to be attached to 9,) I cut an elongated hole and introduce therethrough the rod 1, that has a head at its upper end, and in the metal of the holder g a dome-shaped rise is formed at m to contain this head, when the hinge is riveted .to the holder 9. The other end of the rod passes through a hole in the ratchet-cap c, and the end thereof is bent up so that it cannot draw out, but retains the chimney-holder when turned back in the position shown in Fig. 1, but when the chimneyholder is turned down to place this rod Z slides through the hole in o, and the turning movement, consequent on the change of angle between the holder and rod, is allowed for by the elongation of the hole in 76, the head of the rod being confined in its place between the hinge and holder.

What I claim, and desire to secure by Let- I rod is allowed to turn as the chimney-holder is moved on its hinge, as set forth.

In witness whereof I have hereunto set my signature this 8th day of January, 1864.

L. J. ATWOOD.
